Systems and Methods for Online Gain Calibration of Digital-to-Time Converters - A simplified explanation of the abstract

This abstract first appeared for US patent application 18534861 titled 'Systems and Methods for Online Gain Calibration of Digital-to-Time Converters

Simplified Explanation

The patent application describes a system that includes a digital-to-time converter (DTC) and a calibration DTC, a latch comparator, an average computation module, and a digital controller. The system is designed to receive DTC codes and clock signals, provide output signals, compare the timing of the output signals, compute an average value, and control the DTC codes accordingly.

• The system includes a first digital-to-time converter (DTC) that receives a DTC code and a clock signal to provide an output clock signal.
• A calibration DTC is also part of the system, receiving a calibration DTC code and a second clock signal to provide a calibration output signal.
• A latch comparator in the system determines which of the output clock signal and the calibration output signal is received first.
• An average computation module calculates the average value of the latch comparator outputs.
• A digital controller receives the average value and controls the DTC code and the calibration DTC code accordingly.

Original Abstract Submitted

A system includes a first digital-to-time converter (DTC) adapted to receive a first DTC code and a first clock signal. The first DTC provides an output clock signal. The system includes a calibration DTC adapted to receive a calibration DTC code and a second clock signal. The calibration DTC provides a calibration output signal. The system includes a latch comparator which provides outputs indicative of which of the output clock signal and the calibration output signal is received first. The system includes an average computation module which provides an average value of the outputs of the latch comparator. The system includes a digital controller adapted to receive the average value. The digital controller provides the DTC code and the calibration DTC code.
